FIG. 3.

The concentration of hydrogen peroxide in microdialysates from the gastrocnemius muscles of mice over five 15 min collections at rest, followed by 15 min of isometric contractions and a further 15 min at rest (A). A schematic diagram of the microdialysis probe is also shown (B), together with the calculation of interstitial hydrogen peroxide from microdialysate values and the values for the recovery of hydrogen peroxide across the probe obtained in preliminary studies. Data derived from Vasilaki et al. (76).
